摘要：

We present a solution of the mu problem within a supersymmetric model based on the SU(2)(L) x SU(2)(R) x U(1)(B - L) gauge group. We show that this solution implies a built-in hybrid inflationary scenario, which may result in a successful baryogenesis via leptogenesis. Baryon number is essentially conserved as a result of an R-symmetry. Neutrinos with mass in the eV range can provide the 'hot' dark matter component. (C) 1998 Published by Elsevier Science B.V.
